[jira] [Commented] (NETBEANS-2877) Servlet annotations not working
[ https://issues.apache.org/jira/browse/NETBEANS-2877?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16889686#comment-16889686 ]
Geertjan Wielenga commented on NETBEANS-2877:
---------------------------------------------
If it works with JDK1.8u221 in 8.2, try with JDK1.8u221 in 11.0. Better yet, use 11.1, not released yet, but close, using vc2:

> Servlet annotations not working
> -------------------------------

> Key: NETBEANS-2877
> URL: https://issues.apache.org/jira/browse/NETBEANS-2877
> Project: NetBeans
> Issue Type: Bug
> Environment: Win10, Apache NetBeans IDE 11.0 (Build incubator-netbeans-release-404-on-20190319), apache-tomee-webprofile-8.0.0-M3 or TomCat 9.0.22, or Glassfish 5.0.1
> Reporter: Ernestas Gruodis
> Priority: Major

> Some kind of nightmare - can not launch primitive servlet on `apache-tomee-webprofile-8.0.0-M3` (the same with TomCat 9.0.22 and Glassfish 5.0.1) and `Apache NetBeans IDE 11.0 (Build incubator-netbeans-release-404-on-20190319)` by using servlet annotations.. Using JDK11. Here is the code:

> @WebServlet(name = "NewServlet", urlPatterns =
> {"/meow"})
> public class NewServlet extends HttpServlet {
>
> /**
> * Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods.
> *
> * @param request servlet request
> * @param response servlet response
> * @throws ServletException if a servlet-specific error occurs
> * @throws IOException if an I/O error occurs
> */
> protected void processRequest(HttpServletRequest request, HttpServletResponse response)
> throws ServletException, IOException {
> response.setContentType("text/html;charset=UTF-8");
> try ( PrintWriter out = response.getWriter()) \{ /* TODO output your page here. You may use following sample code. */ out.println("<!DOCTYPE html>"); out.println("<html>"); out.println("<head>"); out.println("<title>Servlet NewServlet</title>"); out.println("</head>"); out.println("<body>"); out.println("<h1>Servlet NewServlet at " + request.getContextPath() + "</h1>"); out.println("</body>"); out.println("</html>"); }

> The goal is to declare servlets only by annotations, like `@WebServlet(name = "NewServlet", urlPatterns = \{"/meow"}
> )`.
> Tested on NetBeans 8.2 with JDK1.8u221 - all works as expected. I suspect the problem is in Apache NetBeans 11, even if project JDK is set to 8 (also source/binary format).
